目的：探討介入墊上核心訓練後，對慢性下背痛患者椎穩定肌力、肌耐力、局部血流、運 動知覺及功能障礙之影響。方法：以30名慢性下背痛女性患者為研究對象。隨機分成墊上核心 訓練組（MST）及控制組（C），前測完成後，MST組訓練為期6週、每週2次、每次60分鐘，並 於訓練後的1週內後測。資料以混合設計二因子變異數分析統計。結果：一、MST組訓練後疼痛 自覺及背肌肌電反應時間顯著下降，且優於C組；二、MST組訓練後氧合血紅素及血氧飽和度顯 著下降，且背肌力矩峰值及本體感覺復位度均顯著進步。結論：參與6週墊上核心訓練者比未介 入訓練前顯著改善下背痛患者疼痛、運動知覺、局部血流及肌力，尤其在疼痛及背肌肌電反應 時間的改善也比未經訓練者來得佳。

Purpose: To investigate the effectiveness of mat science training (MST) in improving the lumbar stability, muscle strength, muscular endurance, local blood flow, kinesthesia, and dysfunctions in patients with chronic lower back pain. Methods: Thirty women with chronic lower back pain participated in the study and were randomly assigned to MST group and control group. The MST group completed a 6-week program involving two 60-minute MST sessions per week after pre-test. Upon completing the program, the participants were tested again within one week. Data were analyzed using a two-way mixed design analysis of variance. Results: The visual analog scale and response time of the MST group was significantly decreased, and significantly lower than that of the control group. The oxy-Hb and SpO2 were decreased significantly, and the isokinetic peak torque of lumbar muscles, re-positioning accuracy were improved significantly in MST group. Moreover, compared with the control group, the response time was significantly higher in MST group after training. Conclusion: The 6-week MST program significantly improved the perceived pain, kinesthesia, local blood flow, and lumbar muscle strength. Moreover, the significant improvements in pain and response time was found for the participants who completed training.
